A pair of animal rights activists were subpoenaed to testify before a federal grand jury, presumably investigating the release of thousands of minks from a pair of Utah farms.

Jordan Halliday, 21, and another activist were called to testify before the secret panel on Wednesday.

"I have no idea what it's about," Halliday told the Deseret News just before walking into the federal courthouse.

The young man was accompanied by his father and an attorney, having been handed a grand jury subpoena two weeks ago from an FBI agent.
Halliday's father said the federal agent asked him about the August 2008 release of 300 minks from a South Jordan farm. Halliday said he had refused to talk to the FBI.
He spent about 30 minutes before the grand jury on Wednesday, refusing to answer questions by claiming the subpoena hadn't been properly served on him.

Federal authorities are investigating the release of minks at farms in South Jordan and Kaysville last year. More than 6,000 minks were released from Kaysville's Lodder Mink Farm in September.
The Animal Liberation Front claimed responsibility for the raid, saying in a communique that breeding records were destroyed and trucks and equipment were vandalized by its "soldiers."

The group also said one "soldier" also claimed responsibility for 300 minks being released from McMullen Mink Farm in South Jordan in August.
